.To aZZ whom it may concern;

Be it known that I, HENRY MARTEN, a citizen of the United States,residing at Toledo, county of Lucas, State of Ohio, have invented acertain new and useful Improvement in Door-Frames for Cooling-Rooms; andI declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to door-frames for cooling-rooms.

It has for its object an improved frame in which the floor or'sill is ona level with the floor of the interior of the cooling-room, icebox, orrefrigerator.

In the drawings, Figure 1 is a perspective showing the frame inposition. Fig. 2 shows the several parts which constitute the front ofthe room. Fig. 3 is a perspective of the frame. Fig. 4 is a frontelevation with the door-frame removed.

The front frame of the room or box is made of planking A and B, whichmay be in any desired number of pieces grooved and united by a tongue 1,which engages in the grooves of adjacent pieces. Behind the planks A andB, which are horizontal planks, are ver tical planks 4 5 6. Through thewall thus formed is a rectangular opening with a deep rabbet extendingacross the top' and down each side. This rabbet is formed by allowingthe lining layer (the Verticals 4 5 6) to extend in, inclosing anopening that is smaller through the lining layer than is the openingthrough the facing layer of planks. The opening through the facing-plankextends below the upper edge of the floor 16. The side planks 9 10,which stop at the upper edge of the floor 16, and the front surface 162of the floorplank form the vertical face of a rabbet that extendsacrosstheopening at the bottom thereof.

The dotted lines about the door-opening in Fig. 4 indicate the partcovered by the frame when in position, and in this view is clearly shownthe difference in elevation between the upper edge of that portion ofthe plank Awhich lies below the door-space and the upper edge of thefloor 16. This equals the thickness of the tread portion or facing 178of the frame, so that when the frame is in osiition this facing and thefloor are on a eve The front planks A reach below the upper edge of thefloor 16 andengage on a subfloor 14, on which the entire structurerests. On the subfloor 14, in front of the horizontal plank A, is abatten 15. In the rectangular space is placed a rectangular frame 17.The stiles 171 172 of this frame fill the vertical rabbets in front ofthe faces 7 9 and 8 10, the rail 173 fills the rabbet across the top ofthe opening, and the sill 174 fills the rabbet in front of face 162 ofthe opening. The inner faces of the frame are flush with the inner faceswhich bound that part of the opening that extends through thelining-plank. The facings 175 176 177 178 engage closely against thefronts of the planks A and B, and the opening through the finished wallis without obstruction, and especially is the sill entirely level withthe floor of the room.

A door (not shown) closes the opening.

What I claim is 1. In combination with a laminated wall provided withapertures of different size in adjacent layers, and with a floor ortionarrangedto be supported above the foundation-floor portion, there beingan air-space therebetween, a door-frame having facingpieces adapted toenga e over theedges of the opening in the outer ayer of the wall, andinwardly-extending portions complementary to said facing-pieces, adaptedto occupy the space intervening between the edges of the opening in theouter layer and the edges of the opening in the inner layer of the wall,and to lie with their exposed surfaces flush with the edges of theopening through the inner layer of the wall, substantially as described.

2. In combination with thelaminated front wall of a refrierator-building, a floor portion spaced from t e foundation of thestructure, a door-frame set in an opening in said wall, having facingportions adapted to engage over the edges of said opening, andinwardlybeing in the same plane and continuous with extending portionsof less depth than the the floor portion, substantially as described. 10thickness of the wall, the exposed faces of In testimony whereof I signthis specificathree of said inwardly-extending portions betion in thepresence of two witnesses.
